The part list consists of one Arduino, two resistors, and one IR emitter. That’s right, an emitter. When an LED (IR or otherwise) is reverse biased it can act as a light sensor.

We’ve featured loads of IR Arduino projects and they are all exciting and unique. The projects spring from a specific need or problem where a custom infrared remote control is the solution. [… ...

Arduino Based Wireless Intrusion Detection Using IR Sensor and GSM Intrusion Detection Systems (IDS) strive to catch computer system intrusion & utilize by any garnering and analyzing data.

The sensor can provide 1080p (1920x1080) resolution at 60 frames per second (fps) or 720p (1280x720) at 90 fps, via a 2-lane MIPI serial output. The OH02A1S also integrates 2 kilobits of one-time ...
